HENRY ROBINSON, OF LINDENHURST, NEW YORK.

v y v sLIcING To all 'whom it may concern.'

VBe it known that l, HENRY ROBINSON, a

citizen of the United States, residing in Lindenhurst, Long Island', New York, have invented certain new and useful Improvements in Slicing Machines, of which the following is a specification.

The present invention relates to an improved vegetable slicing and cutting machine by the operation of which potatoes, beets, carrots, turnips, etc., are sliced without material breakage of the slices, and are discharged from below the cutting element as fast as the slices are formed. 1t is one advantage of this machine that the thickness of the slices produced can be quickly and easily regulated within a comparatively wide range.

Another advantage of the machine is found in the fact that it lends itself readily to the cutting of vegetables into strips, as for French fried potatoes, for instance that the machine may be used for forming either slices or strips. Y

A preferred form of the invention is shown in the accompanying drawings, in which Figure 1 is a side elevation of the machine with half of the casing removed' to show the interior, Figure 2 is a top plan view of directing abutment, Figure 3 is a plan view of the cutting element, Figure 4 is a side elevation of the same, and Figure 5 shows a part of the same in elevation as seen at right angles to the view in Figure 4.

The main casing of the machine is preferably supported upon the legs 10, and is preferably made in two parts 11 and 12, the latter directly attached to the legs and the former fitting down on the part 12 as shown in Figure 1.

`Within the lower part 12 is fixed a spider 13, having a hub 14 serving as a bearing for the shaft 15 of the revolving cutting element. A. pulley 16 on the shaft 17 carried in the bearing 18, drives the shaft 15 through the medium of two beveled gears 19 and 20.

The cutting element carried on the shaft 15 has a fixed, and preferably horizontal and plane portion 21 and an inclined or inclinable portion 22. This latter is preferably movable so as to permit of regulating the thickness of the slices cut, but it is within the broad invention to make the same fixed in position where only one thickness of slice is desired. t'

MACHINE.

Application ined February 19, 1924. serial No. 693,739. `f Y' *i lt is preferred to form each cutting element, as shown with two fixed portions21 on opposite sides of the element and two corresponding inclined portions placed between the fixed portions on each side. i

T:flach fixed portion of the cutting velement hasone substantially radial edge supplied "l with an adjustable knife 23, and another edge 24 at 'right' angles' to 'the 'knife edge which latter lits snugly against oneedge yof the inclined portion corresponding to the opposite knife.

Each inclined portion of the cutting element, in Vaddition to the edge at 24, has another straight edge 25 placed parallel with one of the knives 23 and preferably rounded, as shown. Each of these inclined portions is mounted on ra pivotal pin 26 located close to the circula-r perimeter of the Ycutting element on the edge 24; and near itsfedge 25 each portion 22 'is supportedin the manner shown in Figures 4 and 5. For this purpose a pin 27 is pivotally connected with the part 22 by means of the ears 28 and pin 29.v Thepin 27 is preferably threaded and is adjustably supported on a bracket 30 by means of two nuts 31 and 32.

'l/Vhen the nuts S1 and 32 are. properlyv manipulated, the pin 27 Ais raised or lowered and thepart 22 'tilts around an axis parallel to theedge 25 and 'knife 23. A possible to vary the position of the part 22 so as to regulate the thickness of the slice that is cut. while always preserving the parallelism of the edge 25 and the corresponding knife 23.

It will be seen that the structure described involves a radical departure from the types of rotary slicers hitherto in use, in that instead of regulating the thickness of the slices produced by raising and lowering the knives, this regulation is accomplished by raising and lowering the surface of the disc opposite each knife in such a way as always to preserve the parallelism of the opposed edges. The result of this is that the slices are never bent as they pass under the knives, and comparatively thick slices can therefore be cut without danger of breaking.

The upper portion 11 of the stationary casing is provided with a stationary member which serves to lead or direct the vegetables onto the cutting member, and also to provide an abutment against which the vegetables are crowded by the action of the cutter, so that the knife 23 may be made effec- This makes it'l tive. It may, thelefOle l5@ .HPPTOPTMGIY' machine is clearly shoWnin Figures land:

2. As there shown, it includes a central hub 38 which tapers upward and expands laterally to an edge 34 at the top, Which occupies a diametrical position Within the cylinder 1l. Viewed in plan, this feature includes two Wings S5 andy 36 Whichoccupy diametrically opposite quadrants (although Wings covering an angleV other than` a right angle are Within the invention)=` TheA outer edges of these Wings preferably fit against the inner surfaceof thecylinder and sweep down Ward fromthe extremities of the edge 34 to the respective extremities of the lower,r horizontal, Wing edges 371 and 38; which, to

gether With-the bottom ofthe hub 33, come very close to the top face of they cutting element. Lugs 39are preferably. provided, by ineans of Whiclrthe Whole device may be se cured to the. casing ll by bolts 40.

Upon chargingV the machine, thev vegetables are dropped into the top of thefcas ing ll, and those that fallupon either Wing (as tend to slideoff at right` anglesto its edge, and thus crowdthe vegetables ly.- ing on the revolving cutting member undery the other Wing (as'). The action of the cutting member aids in this crowding against the under side ofl the Wings which act by virtue of their slopingl position. to force the vegetables' down the inclined porL tion off the cutting member and against the revolving knives. T-he thickness of the resulting slices will depend upon the degreel of inclination. ofthe portion-22 of the cutting member; and, owing to theposition oft the knives and the ai'nple space afforded immediately in front of each knife, the slices Will never be materially bent. There Will, therefore, be substantially no breakage of the slices. V

The operation is continuous, as the machine can be charged While the cutter is operating, the sliced vegetables dropping from the bottoni as fastfas they are chargedy at the top.

Tf it isdesired to cut the vegetables into strips, as for Frenchfried potatoes, additional parallel upright blades 4l may be provided in the inclined portions 2Q of the'4 They should be curved This apparatus may. bemodilied inmany Wayswithout. departing from the scope of the invention, which is not limited tothe details herein shown and described.

lVliat is claimed is In a slicing ymachine a casingand a reifoluble cutting element comprising' in com-A binationa iiXed knife bearing portion, a por` tion pivotally mounted on said lined portion,n a bracket under the cutting. element. and a pin supported by said bracket and pivotally connected with the pivotally mount'- yed portion aforesaid.

In testimonyV whereof` I- have hereto 'i set my. hand on this lltli day of February, 19%.
